CHARLES B. HAZARD, OF XENIA, OHIO.

STRAW-STACKER.

SEECIFICATION forming part or Letters Patent No. 703,414, dated July 1, 1902.

Application filed April 15, 1901. Serial No. 55,807. (No model.)

To all whom, it may concern:

Be it known that 1, CHARLES B. HAZARD, a citizen of the United States, and a resident of Xenia, in the county of Greene and State of Ohio, have invented certain new and useful Improvements in Straw-Stackers, of which the following is a specification.

My invention relates to that class of stackers commonly called pneumatic stackers, in which the straw is forced from the thresher or separator through a cylindrical or tubular delivery-pipe by'an air-blast from any suitable fan or blower.

The object of the invention is to provide a simple and efficient form of stacker which can be folded into compact form for transportation, can be readily extended to any desired length, and which can be easily manipulated. The invention resides in the particular 0on struction and arrangement of various parts hereinafter set forth, and particularly pointed out in the claims.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of the stacker extended and ready'for use. Fig. 2 is an enlarged View of the outer end with the supporting-arm folded and the tubular sections telescoped one within the other. Fig. 3 is a side elevation of the same. Fig. 4 is a plan View of'Fig. 1. Fig.5 is a detail view of an operating member or clamp carried by one of the tubular sections. Fig. 6 is a detail view in elevation of the windlass-supportin g frame. Fig. 7 is an end View of the device shown in Fig. 5. Fig. 8 is a side View. Fig. 9 is a de tail of a stop device on the operating-cord; and Fig. 10 is a view similar to Fig. 5, but showing the arms thereof in a diiferent position.

In the drawings, 23 indicates a suitable base, which is preferably in the form of a turntable and which is usually connected-to or carried by the thresher or separator in the manner well understood by those skilled in the art. As this forms no part of the present invention, further description thereof is deemed unnecessary. An elbow-*section-24 is carried by this base, to the horizontally-turned end of which is connected a tubular section 25 of the delivery tube or spout. This tubular spout or tube comprises a plurality of tubular sections 25, 26, and 27, which fitone within the other, so as to telescope and to be capable of being extended or contracted, as desired and according to the requirements of the work. The outer section 27 may have a downwardlycurved end, as shown. In order to support these sections, I provide above them a horizontal beam composed of twoparts hinged together, so as to be capable of being folded one upon the other when the tubular sections are not extended. I have referred to this beam as folding, and it willbe understood that hereinafter when I use the term folding I mean the doubling over of the parts one upon the other in contradistinction to telescoping,when the parts slide one within the other. The rear end of the member 1 of the bar is supported by a strap 28, which encircles the rigid portion of the spout and is bolted at its upper end to the bar. At the front, where the two sections of the bar abut, they are provided with plates 1* and 2 each of which is pivotally connected to lugs or ears formed near the lower end of a vertical post 3. Thus the members 1 and 2 have a hinged or folding connection with each other through the post,

- and the post is also capable of folding over,

so that both the member 2 and the post 3 may be folded back on top of the member 1, as

clearly shown in Fig. 3. In order to strengthen the beam, stay-rods 4 and 5 are provided.

The rod 4: has one end 4 pivotally connected to the upper end of the post 3 and its outer end passed through the eye of a suitable bracket 4:", and a nut 6, threaded on the rod,

serves as an adjustable stop. The rod 5 is likewise pivotally connected to the upper end of the post 3 at 5 and has its opposite end passed through the eye .of a bracket 5 and provided with an adjustable stop-nut 7.

If desired, additional folding braces may be pivotally connected both to the rods at and 5 and the members 1 and 2, as indicated at 8, 9, 10, and 11.

For holding the beam and telescoping sections elevated and adjusting them in any desired degree I provide a frame composed of members 13, 14:, and 15, mounted upon the base 23 and braced by a suitable brace-rod 14*.

A pulley 20 is connected by a wire or rope 21 with an eye 22 on the member 1 of the beam. A rope 10 has one end connected to the cross-bar 14 of the frame, and from this point the rope passes through the pulley 20 and then back over a pulley 15 and down to a drum 17 on a shaft 16, which is provided with a suitable operating-crank 1S.

lhe telescoping members of the tubular spout or delivery-pipe are connected with the supporting-bar by hangers 2!), 30, and 31, which are provided at their upper ends with overturned or hooked portions engaging tracks or rails 32 on opposite sides of the supporting-bar, as clearly shown in Fig. 2.

In order to move the telescoping sections out and in, I provide a cord 36, connected with the section 26 by an automatically-detachable connection, hereinafter described, and havinga permanent connection with the bracket 31 of the outer section 27. The inner end 36 is connected to a suitable drum. (Not shown.) The opposite end is passed around a pulley 37 on the outer end of the supportingbar and thence back through suitable guides in the folding braces and post to a drum 33, provided with a suitable handle 31. Thus, supposing the parts to he in the position shown in Fig. l, by drawing upon the end 36' of the cord 36 the section 26 would be drawn back, carrying with it the section 27, (the parts being extended to their full limit.) As soon as section 26 reaches the limit of its inward movement the cord 36 is automatically disconnected therefrom, and the continued pull upon the cord draws the section 27 in. Conversely, when the drum 33 is operated the opposite end of cord 36 is drawn upon, whereby section 27 is first drawn outwardly, and after it has moved out a certain distance on section 26 the cord is automatically engaged with section 26, moving it out likewise.

The automatic connection between the cord 36 and the section 26 will now be described, referring to Figs. 5 to 10, inclusive: Upon a suitable plate which is secured to the rear end of the section 26 are pivoted a pair of arms 38 and 39, the rear ends of which are normally drawn toward each other by a spring 41. These arms carry lugs or projections 40, which are in opposition to each other and are adapted to engage with corresponding lugs or shoulders 42 on a stop-piece 4.2 on or carried by the cord or cords 36 36. \Vhen the parts are in the position shown in Fig. 1, the smaller end of the piece 42 would be between the lugs or pawls etO, and the lugs 42 would be engaged thereby. When the section 26 is drawn backward, as hereinbefore described, the arms 38 39 will enter between the stationary inclines 43 (see Fig. 4) and be compressed, thereby separating the lugs or pawls 40 and releasing the stop-piece, which is free to continue its movement with the cord. On the movement of the cord in the opposite direction the section 27 is first moved outward by its permanent connection until the shoulder 42 of the stop-piece contacts with the frame carrying the arms 40, when both sections continue their movement in unison.

Having thus described my invention, what I claim is 1. In a straw-stacker, the combination with the telescoping cylindrical tubes or sections,

of a hinged and folding beam supporting the same, substantially as described.

2. In a straw-stacker, the combination with the telescoping cylindrical tubes or sections, of a hinged and folding beam supporting the same and folding braces for said beam, substantially as described.

In a straw-stacker, the combination with the telescoping stacker-sections, of a supporting-beam therefor comprising hinged sections, sliding connections between said beam and telescoping sections, an upright hinged to said beam, and folding truss-rods connecting said upright and beam-sections, substantially as described.

4. In a stacker, the combination with the telescoping stacker-sections, of a sectional supportingbeam therefor, sliding connections between said beam and telescoping sections, an upright hinged to said beam, trussrods extending from the top of said upright to opposite ends of the beam, and folding braces between said rods and the sections of the beam, substantially as described.

5. In a stacker, the combination with the telescoping sections, of a sectional supporting-beam therefor, sliding connections between said beam and said telescoping sections, an upright hinged to said beam, and truss-rods pivotally connected to the upper end of said. upright and having their opposite ends slidingly connected with opposite ends of the beam, substantially as described.

6. In a stacker, the combination with the telescoping stacker-sections, of a folding supporting-beam therefor, sliding connections between the beam and said stacker-sections, an upright hinged to said beam, truss-rods pivotally connected to the upper end of said upright, and extending through eyes at opposite ends of the beam, and nuts threaded on said rods and cooperating with said eyes, substantially as described.

7. In a stacker, the combination with the telescoping stacker-sections, of a supportingbeam comprising two members, an upright at the junction of said members having a hinged connection to each, and truss-rods pivotally connected to the upper end of said upright and slidingly connected to opposite ends of said beam and sliding connections between said beam and stacker sections, substantially as described.

8. In a stacker, a supporting-beam, a plurality of telescoping sections having sliding connections therewith, an operating-cord permanently connected to one of said sections for moving it in both directions,an automaticallysupported thereby, an operating cord or rope having a permanent connection with an outer section, a stop member on said cord, pawls for engaging said stop device, spring-pressed arms'carrying said pawls, and stationary inclines in the path of said arms for operating them to release the pawls. substantially .as described.

In witness whereof I have hereto subscribed my name in the presence of two'witnesses.

CHARLES B. HAZARD.
